Basic Information:

The Huawei eSFP (Enhanced Small Form factor Pluggable) transceiver module, part number 02311SAS, is designed to provide high speed data transmission over Gigabit Ethernet (GE) networks. This module is specifically engineered for use in multi mode fiber optic systems, offering compatibility with existing infrastructure and the ability to support high data rates over short to medium distances.

Specifications:

1. Form Factor: Enhanced Small Form factor Pluggable (eSFP)

2. Data Rate: Gigabit Ethernet (1 Gbps)

3. Wavelength: 850nm

4. Distance: 0.55km (550 meters)

5. Connector Type: LC (Lucent Connector)

6. Fiber Type: Multi mode

7. Part Number: 02311SAS

Transmitter Receiver Characteristics:

1. Transmitter:

  Wavelength: 850nm

  Output Power: Typically around +3dBm to ensure reliable signal transmission over the specified distance.

  Modulation Format: Non return to zero (NRZ) encoding is commonly used for Gigabit Ethernet.

2. Receiver:

  Sensitivity: The receiver's sensitivity is crucial for determining the maximum distance over which the signal can be transmitted without significant degradation. For this module, the sensitivity is typically around  15dBm, which means it can receive signals as low as this level without errors.

  Optical Bandwidth: The receiver is designed to operate within the optical bandwidth that supports 1 Gbps data rates at 850nm.

3. Optical Link Budget:

  The link budget is the difference between the transmitter's output power and the receiver's sensitivity. It accounts for signal loss over the fiber, ensuring that the signal remains strong enough for reliable data transmission.

4. Temperature Range:

  The module is designed to operate within a specific temperature range to ensure consistent performance. This range is typically between 0°C and 70°C (32°F to 158°F) for commercial applications.

5. Environmental Compliance:

  The eSFP module adheres to industry standards for electromagnetic compatibility (EMC) and safety, ensuring it can be used in various environments without causing interference or being affected by it.

6. Compatibility:

  The module is designed to be compatible with a wide range of networking equipment that supports the eSFP form factor, including switches, routers, and other network devices from various manufacturers.

7. Power Consumption:

  eSFP modules typically consume low power, making them energy efficient and suitable for environments where power consumption is a concern.

Conclusion:

The Huawei 02311SAS eSFP module is a high performance, energy efficient solution for Gigabit Ethernet applications requiring multi mode fiber optic connectivity. Its specifications ensure reliable data transmission over distances up to 550 meters, making it ideal for use in data centers, campus networks, and other high speed networking environments.
